MDF vs. Particleboard

Many enclosures that you find at retail stores are made from particleboard, not MDF. MDF is a very dense type of wood made from very small, fiber-like particles. You can see from the pictures above that
particleboard has very large particles, much larger than the particles in MDF. MDF is a much higher quality wood that is recommended by subwoofer manufacturers as well as anyone that knows anything about
getting the most sound out of their subwoofers. We at Klaus Audio want the enclosures that we build to be of the highest quality possible, and that is why we use only MDF for our enclosures.

Another important factor (that has nothing to do with MDF or particleboard) when selecting your enclosure is terminal cups. Quality terminal cups are necessary to ensure
maximum flow from the amplifier to the subwoofers. We use terminal cups with gold-plated posts because gold-plated connectors result in minimal loss of power.

Just remember to keep this information in mind when shopping around and comparing prices of enclosures. The materials used to build the enclosure will make a big difference in the sound quality you'll get from your
subwoofers.
